Intel i7 Pricing

post #1 of 15
Thread Starter 
This question probably makes me sound like a complete n00b but here goes anyways:

Why is the i7-2600K only priced at $300 and the i7-3940XM priced at over $1000?

http://ark.intel.com/products/series/53250
http://ark.intel.com/products/family/65505

They both have 4 cores and 8 threads, but what else makes the 3940M that much better?

Thanks,
My System

First off, one is desktop while the i7-3940xm is designated as a mobile processor.

Also, the desktop model has a TDP of 95W while the mobile model has a TDP of 55W

The i7-3940XM has less thermal output (TDP) than the 2600k, also it is made for laptops. Its more expensive simply because its harder to make and more expensive to make. so to get a profit from it they have to sell it at that price.

Performance wise, they're the same at the same clocks.

Ahh OK Thanks, good to know and makes sense.

How about the i7-3960X compared with the i7-2600K?

Both are made for desktops, right? But the i7-3960X is a lot more expensive. I'm looking at the stats but not sure what makes it that much better (and expensive) than the 2600K?

Thanks,
My System

The 3940XM is an Ivy Bridge part, with all advantages that entails (better iGPU, PCIe 3.0, lower TDP and power usage, better IMC). It's also an Extreme edition part (black stickers are more expensive than blue:o).
It's also a mobile part, though I'm not sure if that matters in and of itself.

As for the 3960X, it's a hexacore extreme edition chip with almost twice the L3 cache, and Intel's flagship (3970X is the only higher part outside Xeons, and that's essentially the same chip with a clock bump).

Thanks,

3960X have 6 cores and 12 threads, 2600K have 4 cores and 8 threads, in heavily threaded operations 3960X can have up to 150% the performance of 2600K at the same clocks, in single thread application there performance would be about the same.

However, the 3930K also have 6 cores and 12 threads, the only difference between it and the 3960X is that 3930K is clocked lower at stock and about $500 cheaper.

They're about the same performance per HZ, but the 3960X has 6 cores and 12 threads compared to the 2600k's 4 cores and 8 threads.

^this! In addition, the 3960x uses a different chipset than Sandy Bridge processors.

Is the chipset more expensive in it self or is it more expensive because its compatible with the CPUs?
